Abstract: 763,662. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 18. 1954 [Oct. 21, 1953], No. 29905/54. Class 100(4) Sheet feeding, and guiding arrangements. In a platen supporting carriage for typewriters and like machines, the lower feeding rollers 100, 102 are carried by rear and forward arms 70, 72 :pivotally mounted between plates 66, 68 of brackets 64 carried on shafts 26, 28, the latter having a cam 74, Fig. 7, which, when operated by crank mechanism 114- 122, engages arm 70, and interconnected arm 72, to move the rollers 100, 102 away from the platen. The arms 70, 72 are biased to wards the platen by torsion strips 86, 88 adjustably mounted by screws 94 in ears 96 projecting from brackets 90, 92 suspended from the shaft 28. To effect adjustment, a guide plate 134, with cut-outs 135, 137 to give clearance of the rollers 100, 102, is pivoted to the upright position shown. Upper feeding rollers 170, Fig. 3, are carried on a bail constructed so it tends to smooth the sheets on to the platen to prevent crinkling. The bail comprises a bar 145 carrying the rollers 170 attached to arms 144, pivotally mounted at 148 on hinge arms 142 themselves pivoted to slide plates 22. When the bail is pivoted clockwise clear of the platen it pivots about 148 until a bearing 152 locks against the hinge arm 142 whereupon both are pivoted as a unit about rod 140, and the surface 166 of a spring arm 146 keeps the bail in raised position. To lower the bail and smooth the sheet against the platen, the bail is pulled to the chain dotted position where cover bearings 176 on the arms 144 engage cover guide cams 178. The bail stays in this position, by pressure of the surfaces 164 of the arms 146, until pushed by the operator past a point 172 whereupon the surfaces 166 act on the bearings 152 to pull the bail and the rollers 170 backwards, guided by rollers 176 and guides 178 so that the sheet is smoothed on to the platen. Platen mounting. The platen 9 is removably mounted in grooves 34 in the slide plates 22 and locked in position by members 40. The slide plates 22 are adjustably mounted as at 23 to the main carriage side plates 7 so that the platen may be moved transverse to its axis to accommodate a large number of carbon copies. Line-spacing arrangements. A carriage return movement automatically effects one, two or three units of line spacing by the pull of a draw tape 184, Fig. 3, on the end 183 of a hook 177, pivoted at 179 and urged counterclockwise by sprung dog 186 against a stop 211. The position of stop 211 is adjustable by means of a lever 196 (Fig. 5 not shown) so that the clockwise travel of the hook 177, and a pawl 212 thereon which is biased towards the platen ratchet 220, effects different linespacing movements of the platen. The pawl 212 is permitted to engage the rate chet 220 by a V-shaped member 228 which pivots clockwise as the hook 177 leaves the stop 211. Platen rotation for all units of line spacing is arrested by a bracket 222.
